It is becoming necessary to prepare.

特開平3−28037号公報JP-A-3-28037

本発明は、照明機能に加えて、乗員を個別に迎える光の演出効果を有する「ウェルカムライト」として機能する車両内照明装置を提供することを目的とする。   It is an object of the present invention to provide an in-vehicle illumination device that functions as a “welcome light” having a lighting effect of individually welcoming an occupant in addition to an illumination function.

本発明は、車両のドアの開閉動作を検出する開閉検出手段と、第1の座席への乗員の着座を検出する着座検出手段と、前記第1の座席の前列に設置されている第2の座席に取付けられた照射手段とを備えた車両内照明装置であって、前記照射手段は、前記第2の座席のクッションパッドを載置及び支持するクッション台座の下面における左右の側部に取付けられる側部照射手段と、前記第2の座席の台座の下面における後部に取付けられる後部照射手段とからなり、前記側部照射手段と前記後部照射手段は、その照射する光が下向きに指向する状態で取付けられており、前記開閉検出手段がドアの開動作を検出すると、前記側部照射手段と前記後部照射手段が点灯し、前記着座検出手段が乗員の着座を検出すると、前記側部照射手段が消灯し、前記後部照射手段のみが点灯することを特徴とする、車両内照明装置である。   The present invention includes an opening / closing detection means for detecting an opening / closing operation of a door of a vehicle, a seating detection means for detecting a seating of an occupant on the first seat, and a second seat installed in a front row of the first seat. In-vehicle illumination apparatus comprising an irradiating means attached to a seat, wherein the irradiating means is attached to left and right side portions of a lower surface of a cushion base on which a cushion pad of the second seat is placed and supported. It comprises a side irradiating means and a rear irradiating means attached to the rear portion of the lower surface of the pedestal of the second seat, and the side irradiating means and the rear irradiating means are in a state in which the irradiated light is directed downward. When the opening / closing detection means detects the opening operation of the door, the side irradiation means and the rear irradiation means are turned on, and when the seating detection means detects the occupant's seating, the side irradiation means Off The only rear illumination means, characterized in that the lighting is a vehicle within the lighting system.

本発明において、第1の座席とは、乗員の着座を検出する着座検出手段(例えば着座センサなど)が取付けられている座席(シート)のことである。第2の座席とは、第1の座席の前の列(好ましくは直前の列)に設置される座席のことであって、照明用の光を照射する照射手段がその台座の下面に取付けられる座席のことである。3列シートタイプの車両を例にとって説明すると、2列目のシート及び/又は3列目のシートを、本発明の「第1の座席」として使用することができる。1列目のシート及び/又は2列目のシートを、本発明の「第2の座席」として使用することができる。   In the present invention, the first seat is a seat (seat) to which seating detecting means (for example, a seating sensor) for detecting the seating of an occupant is attached. The second seat is a seat installed in a row in front of the first seat (preferably in a row immediately before), and an irradiating means for irradiating illumination light is attached to the lower surface of the pedestal. It is a seat. Taking a three-row seat type vehicle as an example, the second-row seat and / or the third-row seat can be used as the “first seat” of the present invention. The first row seat and / or the second row seat can be used as the “second seat” of the present invention.

本発明の車両内照明装置によれば、車両の車室天井部ではなく、第2の座席の台座の下面に照射手段が取付けられる。この照射手段は、照射する光が下向きに指向する状態で取付けられる。このため、車両の車室内に乗員が乗り込んだ場合には、車室内の上方からではなく、車室内の床面側から間接的に光が照射される。この場合、間接照明となるために目に優しいだけでなく、乗員の足下の視認性が高まるために、車室内における安全性が向上する。   According to the in-vehicle illumination device of the present invention, the irradiating means is attached to the lower surface of the base of the second seat, not to the ceiling of the vehicle compartment. This irradiating means is attached in a state where the irradiating light is directed downward. For this reason, when an occupant gets into the vehicle interior of the vehicle, light is indirectly irradiated from the floor side in the vehicle interior, not from above the vehicle interior. In this case, since it becomes indirect illumination, it is not only easy on the eyes, but also increases the visibility of the occupant's feet, so the safety in the passenger compartment is improved.

また、本発明の車両内照明装置によれば、乗員がドアを開けると、開閉検出手段によってドアの開動作が検出され、第2の座席の台座の下面の両側部および後部に備えられた照射手段が点灯し、第2の座席の台座の周囲が明るくなる。このため、夜間などに、乗員が車両に乗り込んだ場合には、座席の周囲が光に包まれたようになるために、座席がまるで浮き上がっているような幻想的な演出効果をもたらす。次いで、乗員が第1の座席に着座すると、その第1の座席の前列に設置されている第2の座席の台座の下面の側部に取付けられた側部照射手段が消灯し、同じく第2の座席の台座の下面の後部に取付けられた後部照射手段のみが点灯する。このため、乗員が第1の座席に着座すると、光が乗員のほうへ近づいてくるかのような演出効果をもたらす。このように、本発明に係る車両内照明装置は、乗員の着座を検出して光の照射態様が変化するので、個々の乗員を個別に迎え入れるような演出効果を発揮する。すなわち、本発明に係る車両内照明装置は、いわゆる「ウェルカムライト」としての機能を発揮することができる。   According to the in-vehicle lighting device of the present invention, when the occupant opens the door, the opening operation of the door is detected by the open / close detection means, and the irradiation provided on both sides and the rear of the lower surface of the base of the second seat is provided. The means is lit and the periphery of the base of the second seat is brightened. For this reason, when an occupant gets into the vehicle at night or the like, the surroundings of the seat are surrounded by light, so that a fantastic rendering effect is brought about as if the seat is lifted up. Next, when the occupant sits on the first seat, the side irradiation means attached to the side of the lower surface of the base of the second seat installed in the front row of the first seat is turned off, and the second Only the rear irradiation means attached to the rear part of the lower surface of the base of the seat is lit. For this reason, when the occupant is seated on the first seat, an effect is produced as if light approaches the occupant. As described above, the in-vehicle illumination device according to the present invention detects the seating of the occupant and changes the light irradiation mode, and thus exhibits an effect of welcoming each occupant individually. That is, the in-vehicle illumination device according to the present invention can exhibit a function as a so-called “welcome light”.

また、本発明は、前記後部照射手段のみが点灯する際に、該後部照射手段の照度が増大することを特徴とする、車両内照明装置である。後部照射手段の照度が増大することによって、乗員が着座したときに光によって出迎える演出効果がより効果的に発揮される。   Further, the present invention is the in-vehicle illumination device characterized in that when only the rear irradiation unit is turned on, the illuminance of the rear irradiation unit increases. By increasing the illuminance of the rear irradiating means, the effect of greeting with light when an occupant is seated is more effectively exhibited.

以下、本発明の実施の形態を図面を参照しながら説明する。
図1は、本実施の形態に係る車両内照明装置を適用したワンボックスタイプの車両を示している。

The in-vehicle lighting device 20 according to the present embodiment functions as a welcome light that exhibits the effect of welcoming the occupant when the occupant who enters the vehicle sits on the seat 6 in the second row.

図2は、1列目の座席4及び2列目の座席6の配置関係を示す側面図であり、座席4に照射手段40が取付けられており、座席6に着座検出手段30が取付けられている状態を示している。図3は、1列目の座席4の斜視図であり、座席全体の輪郭を二点破線で示すとともに、台座12の下面13に取付けられている照射手段40を実線あるいは破線で示している。図4は、2列目の座席6の斜視図であり、座席全体の輪郭を二点破線で示すとともに、クッションパッド10の内部に設置されている着座検出手段30を実線で示している。図5は、1列目の座席4の台座12とその下面13に取付けられている照射手段40の斜視図であり、図6は、1列目の座席4を前方から見た正面図であり、図7は、1列目の座席4を左側から見た側面図である。   FIG. 2 is a side view showing the positional relationship between the first row of seats 4 and the second row of seats 6, in which the irradiation means 40 is attached to the seat 4 and the seating detection means 30 is attached to the seat 6. It shows the state. FIG. 3 is a perspective view of the seat 4 in the first row. The outline of the entire seat is indicated by a two-dot broken line, and the irradiation means 40 attached to the lower surface 13 of the base 12 is indicated by a solid line or a broken line. FIG. 4 is a perspective view of the seats 6 in the second row. The outline of the entire seat is indicated by a two-dot broken line, and the seating detection means 30 installed inside the cushion pad 10 is indicated by a solid line. FIG. 5 is a perspective view of the irradiation means 40 attached to the base 12 and the lower surface 13 of the seat 4 in the first row, and FIG. 6 is a front view of the seat 4 in the first row as seen from the front. FIG. 7 is a side view of the first row of seats 4 as viewed from the left side.

本実施の形態に係る車両内照明装置20は、車両のドア9の開閉動作を検出する開閉検出手段と、前から2列目の座席6への乗員の着座を検出する着座検出手段30と、前から1列目の座席4の台座12の下面13に取付けられた照射手段40とから構成されている。   The in-vehicle lighting device 20 according to the present embodiment includes an open / close detection unit that detects an opening / closing operation of the door 9 of the vehicle, a seating detection unit 30 that detects the seating of an occupant on the seat 6 in the second row from the front, It is comprised from the irradiation means 40 attached to the lower surface 13 of the base 12 of the seat 4 of the 1st row from the front.

開閉検出手段とは、乗員による車両のドア9の開閉動作を検出することのできる手段のことであり、一般に広く使用されているドアスイッチ等がこれに該当する。このようなドアスイッチは、例えば、ドアの開閉に連動して点灯及び消灯するルームライト等に用いられている。もちろん、ドア9の開閉動作を検出できるのであれば、このようなドアスイッチに限らず、既存あるいは周知のあらゆるセンサ類を開閉検出手段として使用することができる。   The opening / closing detection means is means that can detect the opening / closing operation of the door 9 of the vehicle by an occupant, and corresponds to a door switch that is widely used in general. Such door switches are used, for example, for room lights that are turned on and off in conjunction with opening and closing of the door. Of course, as long as the opening / closing operation of the door 9 can be detected, not only such a door switch but also any existing or known sensors can be used as the opening / closing detection means.

着座検出手段30とは、乗員の座席(シート)への着座を検出する手段のことであり、一般に広く使用されている感圧センサ等がこれに該当する。このような感圧センサは、例えば、乗員が着座しているにもかかわらずシートベルトが装着されていないことを表示するための警告ランプ等に利用されている。もちろん、乗員が着座したことを検出できるのであれば、このような感圧センサに限らず、既存あるいは周知のあらゆるセンサ類を着座検出手段として使用することができる。例えば、乗員の体温を検知することで着座を検出することのできる温度センサや、乗員の着座動作そのものを光学的に検出する赤外線センサなどを、着座検出手段として使用することができる。   The seating detection means 30 is a means for detecting the seating of an occupant on a seat (seat), and a pressure sensor or the like that is widely used generally corresponds to this. Such a pressure-sensitive sensor is used, for example, as a warning lamp for displaying that a seat belt is not worn even though an occupant is seated. Of course, as long as it is possible to detect that the occupant is seated, not only such a pressure-sensitive sensor but also any existing or known sensors can be used as the seating detection means. For example, a temperature sensor that can detect the seating by detecting the body temperature of the occupant, an infrared sensor that optically detects the seating operation of the occupant, and the like can be used as the seating detection means.

照射手段40とは、1列目の座席4の台座12の下面13に取付けられる光の照射手段のことである。このような照射手段40としては、例えば、光源としてLEDや電球などを用いたランプが用いられる。この照射手段40は、台座12の下面13の左右の両側部に取付けられる側部照射手段42と、台座12の下面13の後部に取付けられる後部照射手段44とから構成される。   The irradiation means 40 is light irradiation means attached to the lower surface 13 of the base 12 of the seat 4 in the first row. As such an irradiating means 40, for example, a lamp using an LED or a light bulb as a light source is used. The irradiation means 40 includes side irradiation means 42 attached to the left and right sides of the lower surface 13 of the pedestal 12 and a rear irradiation means 44 attached to the rear portion of the lower surface 13 of the pedestal 12.

図3,図5に示すように、台座12の下面13の両側部に取付けられる側部照射手段42は、台座12の下面13の右側部に取付けられた2本のLEDモジュール42a,42bと、台座12の下面13の左側部に取付けられた2本のLEDモジュール42c,42dの合計4本のLEDモジュールから構成されている。台座12の下面13の後部に取付けられた後部照射手段44は、後部における右側に取付けられた2本のLEDモジュール44a,44bと、後部における左側に取付けられた2本のLEDモジュール44c,44dの合計4本のLEDモジュールから構成されている。右側のLEDモジュール44a,44bと、左側のLEDモジュール44c,44dは、それぞれ前後に隣接して2本ずつ取付けられている。
なお、後部照射手段44は、左右2本ずつ、合計4本のLEDモジュール44a〜44dにより構成されている例を示しているが、このような態様に限定するものではない。例えば、後部照射手段44は、左右1本ずつの合計2本のLEDモジュールにより構成してもよく、そして、そのLEDモジュール内の基盤が2列である構成であってもよい。
As shown in FIGS. 3 and 5, the side irradiation means 42 attached to both sides of the lower surface 13 of the pedestal 12 includes two LED modules 42 a and 42 b attached to the right side of the lower surface 13 of the pedestal 12, and It consists of a total of four LED modules, two LED modules 42c and 42d attached to the left side of the lower surface 13 of the base 12. The rear irradiation means 44 attached to the rear part of the lower surface 13 of the base 12 includes two LED modules 44a and 44b attached to the right side in the rear part, and two LED modules 44c and 44d attached to the left side in the rear part. It consists of a total of four LED modules. Two LED modules 44a and 44b on the right side and two LED modules 44c and 44d on the left side are attached adjacent to each other in the front-rear direction.
In addition, although the rear part irradiation means 44 has shown the example comprised by the LED module 44a-44d of a total of four each by two right and left, it is not limited to such an aspect. For example, the rear irradiating means 44 may be constituted by a total of two LED modules, one each on the left and right, and may have a configuration in which the bases in the LED modules are in two rows.

図5に示すように、1列目の座席4を車両内に載置して固定しておくための台座12は、その座席4のクッションパッドを載置及び支持するクッション台座である。この台座12は、合計4本の脚部15a〜15dを持つ平板状の台座であって、鉄板などの金属板が溶接や曲げ加工されて成形されたものである。この台座12の側部及び後部はクランク状に曲げ加工されており、LEDモジュール42a〜42d,44a〜44dを取付けるための取付部14を形成している。LEDモジュール42a〜42d,44a〜44dは、その照射する光が少なくとも下向きに指向する状態で、しかも、脚部15a〜15dが取付けられる面よりも一段上の位置に取付けられる。LEDモジュール42a〜42d,44a〜44dを取付部14に対して取付けるためには、接着剤やビス止めなどのいかなる手段を使用してもよい。なお、台座12の下面13に設置するLEDモジュールの数や位置などは、必要とされる照度や照明態様に応じて適宜変更することが可能である。   As shown in FIG. 5, the pedestal 12 for placing and fixing the first row of seats 4 in the vehicle is a cushion pedestal for placing and supporting the cushion pad of the seat 4. The pedestal 12 is a flat pedestal having a total of four leg portions 15a to 15d, and is formed by welding or bending a metal plate such as an iron plate. The side part and the rear part of the pedestal 12 are bent into a crank shape to form an attachment part 14 for attaching the LED modules 42a to 42d and 44a to 44d. The LED modules 42a to 42d and 44a to 44d are mounted at a position one level higher than the surface on which the leg portions 15a to 15d are mounted in a state where the irradiated light is directed at least downward. In order to attach the LED modules 42 a to 42 d and 44 a to 44 d to the attachment portion 14, any means such as an adhesive or screwing may be used. Note that the number and position of the LED modules installed on the lower surface 13 of the pedestal 12 can be appropriately changed according to the required illuminance and illumination mode.

図5に示すように、1列目の座席4の台座12の周囲には、合成樹脂製のシールド18が取付けられる。このシールド18は、硬質の合成樹脂が射出成形等により板状に成形されたものである。台座12の周囲にシールド18が設置されることにより、照射手段40の周囲がシールド18によって囲まれることになる。このため、照射手段40により照射された光が、下方向以外に散逸して直接眼に侵入することが防止され、車両内照明装置20による間接照明の効果が高められる。また、照射手段40の周囲にシールド18が取付けられることによって、LEDモジュール42a〜42d,44a〜44dが剥き出しになって見栄えを損なうことが防止されている。このシールド18は、有色で不透明の合成樹脂により成形してもよいし、半透明の合成樹脂(例えばポリカーボネートなど)により成形してもよい。   As shown in FIG. 5, a synthetic resin shield 18 is attached around the base 12 of the seat 4 in the first row. The shield 18 is made of a hard synthetic resin formed into a plate shape by injection molding or the like. By installing the shield 18 around the base 12, the periphery of the irradiation means 40 is surrounded by the shield 18. For this reason, it is prevented that the light irradiated by the irradiation means 40 dissipates to the direction other than the downward direction and directly enters the eye, and the effect of indirect lighting by the in-vehicle lighting device 20 is enhanced. Moreover, by attaching the shield 18 around the irradiation means 40, the LED modules 42a to 42d and 44a to 44d are prevented from being exposed and deteriorating in appearance. The shield 18 may be formed of a colored and opaque synthetic resin, or may be formed of a translucent synthetic resin (for example, polycarbonate).

照射手段40の光源としては、LED以外にも、例えば、蛍光灯、電球(バルブ)等のあらゆる光源を用いることができる。中でもLEDは、電力消費量が少なく、且つ球切れの恐れが無いため、照射手段40の光源として好適に用いることができる。また、光源としてLEDを用いることによって、照射する光の量(照度)のコントロールが容易になるという効果が得られる。照射手段40から照射される光の色は特に限定されず、白色の他、赤色、青色、緑色などの有色であってもよい。   As a light source of the irradiation means 40, all light sources, such as a fluorescent lamp and a light bulb (bulb), can be used besides LED. Among them, the LED can be suitably used as a light source of the irradiation unit 40 because it consumes less power and there is no fear of running out of a bulb. Further, by using the LED as the light source, an effect that the amount of light to be irradiated (illuminance) can be easily controlled can be obtained. The color of the light irradiated from the irradiation means 40 is not specifically limited, In addition to white, colored colors, such as red, blue, and green, may be sufficient.

また、台座12に設けられている4本の脚部15a〜15dの周囲には、図2に示すように、必要に応じて合成樹脂製のカバー16を取付けることができる。このカバー16は、台座12の脚部15a〜15dを覆い隠すために設けられるものであり、照射手段40により照射された光を遮らないように、LEDモジュール42a〜42d、44a〜44dを取付けるための取付部14よりも内側に取付けられる。   Further, as shown in FIG. 2, a synthetic resin cover 16 can be attached around the four legs 15a to 15d provided on the base 12, as required. The cover 16 is provided to cover the legs 15a to 15d of the base 12, and is used to attach the LED modules 42a to 42d and 44a to 44d so as not to block the light irradiated by the irradiation means 40. It is attached to the inner side of the attachment part 14.

以下、車両内照明装置20の照明態様について説明する。
まず、車両2に乗り込もうとする乗員によってドア9が開けられると、開閉検出手段によってドア9の開動作が検出される。これにより、側部照射手段42及び後部照射手段44が点灯する。具体的には、側部照射手段42を構成する4本のLEDモジュール42a〜42dのすべてが点灯し、さらに、後部照射手段44を構成する4本の44a〜44dのうち、後側の2本のLEDモジュール44b,44dが点灯する(以下、照明態様Aとする)。
つぎに、乗員が2列目の座席6に着座すると、着座検出手段30によって乗員の着座が検出される。これにより、側部照射手段42が消灯し、後部照射手段44のみが点灯する。具体的には、側部照射手段42を構成する4本のLEDモジュール42a〜42dのすべてが消灯し、後部照射手段44を構成する2本のLEDモジュール44b,44dが点灯した状態が維持される(以下、照明態様Bとする)。
そして、ドア9が閉じられると、開閉検出手段によってドア9の閉動作が検出される。ドア9の閉動作が検出されてから一定時間(例えば、15〜30秒程度)経過後に、予めその一定時間が設定されているタイマーによって、後部照射手段44が消灯する。
Hereinafter, the illumination aspect of the in-vehicle illumination device 20 will be described.
First, when the door 9 is opened by an occupant trying to get into the vehicle 2, the opening / closing detection means detects the opening operation of the door 9. Thereby, the side part irradiation means 42 and the rear part irradiation means 44 light. Specifically, all of the four LED modules 42 a to 42 d constituting the side irradiation unit 42 are turned on, and two of the four 44 a to 44 d constituting the rear irradiation unit 44 are arranged on the rear side. LED modules 44b and 44d are turned on (hereinafter referred to as illumination mode A).
Next, when the occupant is seated on the seat 6 in the second row, the seating detection means 30 detects the occupant's seating. As a result, the side irradiation means 42 is turned off, and only the rear irradiation means 44 is turned on. Specifically, all of the four LED modules 42 a to 42 d constituting the side irradiation unit 42 are turned off, and the two LED modules 44 b and 44 d constituting the rear irradiation unit 44 are kept on. (Hereinafter referred to as illumination mode B).
When the door 9 is closed, the closing operation of the door 9 is detected by the open / close detection means. After a predetermined time (for example, about 15 to 30 seconds) has elapsed since the closing operation of the door 9 was detected, the rear irradiation unit 44 is turned off by a timer set in advance.

照明態様A及び照明態様Bを実現するためには、車両の車室内の照明を制御することのできる公知の制御手段を用いることができる。例えば、車両2の内部に設置される電子機器用の制御ユニットなどを用いることができる。この制御ユニットによって、開閉検出手段からの検出信号及び着座検出手段30からの検出信号を受信して、この受信した信号に基づいて、側部照射手段42及び後部照射手段44をそれぞれ点灯及び消灯させるための制御信号を出力させることができる。   In order to realize the lighting mode A and the lighting mode B, a known control unit capable of controlling the lighting in the vehicle interior of the vehicle can be used. For example, a control unit for an electronic device installed inside the vehicle 2 can be used. The control unit receives the detection signal from the open / close detection means and the detection signal from the seating detection means 30, and turns on and off the side irradiation means 42 and the rear irradiation means 44 based on the received signals. A control signal can be output.

照明態様Aにおいては、1列目の座席4の台座12の両側部および後部から光が照射される。これにより、台座12の周辺が明るくなる。その結果、車両2に乗り込んだ乗員の足元の視認性が向上し、乗車時の安全性が向上する。また、夜間に車両2に乗り込んだ場合には、台座12の周囲のみが明るくなるので、座席4がまるで光の中で浮き上がっているかのような幻想的な演出効果をもたらす。   In the illumination mode A, light is irradiated from both side portions and the rear portion of the base 12 of the seat 4 in the first row. Thereby, the periphery of the base 12 becomes bright. As a result, the visibility of the feet of the occupants who have entered the vehicle 2 is improved, and the safety when riding is improved. Further, when the vehicle 2 is boarded at night, only the periphery of the pedestal 12 is brightened, which brings about a fantastic effect as if the seat 4 is floating in the light.

照明態様Bにおいては、1列目の座席4の台座12の後部から強い光が照射される。この光は、2列目の座席6に着座した乗員の足下を照らすので、乗員の足元の視認性が向上し、乗員は足元に置いた荷物などを容易に整理したりすることができる。   In the illumination mode B, strong light is irradiated from the rear part of the base 12 of the seat 4 in the first row. Since this light illuminates the feet of the occupants seated in the second row of seats 6, the visibility of the feet of the occupants is improved, and the occupants can easily organize the luggage placed on the feet.

本実施の形態に係る車両内照明装置20は、照明態様Aから照明態様Bにその照明態様が切り替わることによって、乗員の足元の視認性を向上させることができるだけでなく、車両2に乗り込んだ乗員を迎え入れるような演出効果を発揮する。
すなわち、照明態様がAから照明態様Bに滑らかに切り替わることによって、座席6に着座した乗員にとっては、前列の座席4の台座12の両側部から後部に向かって光が移動するかのように見える。これにより、座席6に着座した乗員に向かって、光が移動して近づいて来るかのような演出効果が発揮される。
The in-vehicle lighting device 20 according to the present embodiment can not only improve the visibility of the feet of the occupant by switching the lighting mode from the lighting mode A to the lighting mode B, but also the occupant who has boarded the vehicle 2 Shows the effect of welcoming you.
That is, by smoothly switching the lighting mode from A to lighting mode B, it appears to the occupant seated in the seat 6 as if light moves from both sides of the base 12 of the seat 4 in the front row toward the rear. . As a result, the production effect as if the light is moving toward the occupant seated on the seat 6 is exerted.

上記の照明態様Bに代えて、次のような照明態様を実施することもできる。すなわち、乗員が2列目の座席6に着座すると、着座検出手段30によって乗員の着座が検出される。これにより、側部照射手段42が消灯するだけでなく、後部照射手段44の照度が増大する。具体的には、側部照射手段42を構成する4本のLEDモジュール42a〜42dのすべてが消灯し、後部照射手段44を構成する4本のLEDモジュール44a〜44dのうち、まだ点灯していなかった2本のLEDモジュール44a,44cが点灯する(以下、照明態様Cとする)。
照明態様Aから照明態様Cに切り換わることによって、光の移動態様がより自然に見えることになる。この結果、乗員を出迎える演出効果がより効果的に発揮される。
Instead of the above illumination mode B, the following illumination mode can also be implemented. That is, when the occupant is seated on the seat 6 in the second row, the seating detection means 30 detects the occupant's seating. This not only turns off the side irradiation means 42 but also increases the illuminance of the rear irradiation means 44. Specifically, all of the four LED modules 42a to 42d constituting the side irradiation means 42 are turned off, and the four LED modules 44a to 44d constituting the rear irradiation means 44 are not yet turned on. The two LED modules 44a and 44c are turned on (hereinafter referred to as illumination mode C).
By switching from the illumination mode A to the illumination mode C, the light movement mode looks more natural. As a result, the effect of welcoming the passenger is more effectively exhibited.

車両内照明装置20は、車両2に設置される各座席に設置することが可能である。車両内照明装置20を座席毎に設置した場合には、車両2に乗車する各乗員の着座のタイミングに合わせて照明態様が切り替わるので、乗員を個別に迎えるウェルカムライトとして機能することができる。   The in-vehicle lighting device 20 can be installed in each seat installed in the vehicle 2. When the in-vehicle lighting device 20 is installed for each seat, the lighting mode is switched in accordance with the seating timing of each occupant who rides on the vehicle 2, so that it can function as a welcome light that welcomes the occupant individually.

側部照射手段42及び後部照射手段44は、その照射する光の少なくとも一部が下方向に指向するように設置されている。このため、照射された光が車室内の床面で反射するために、照明方式が間接照明となる。この場合、照射された光が乗員の目に直接侵入しないので、目のちらつきや眩しさが抑えられている。そのため、乗員の安全性が確保されるだけでなく、落ち着いた印象でしかも高級感のある演出効果がもたらされる。   The side irradiating means 42 and the rear irradiating means 44 are installed so that at least a part of the irradiated light is directed downward. For this reason, since the irradiated light is reflected on the floor surface in the passenger compartment, the illumination method is indirect illumination. In this case, since the irradiated light does not directly enter the eyes of the occupant, flickering and dazzling eyes are suppressed. For this reason, not only is the safety of the passengers secured, but a calm impression and a high-class production effect are brought about.

なお、本発明は、上記実施の形態に限定されるものではない。
例えば、照明態様Aから照明態様Bに切り替わるときに、側部照射手段42を構成する4本のLEDモジュール42a〜42dが一斉に消灯するのではなく、前側のLEDモジュール42a,42cがまず消灯し、次いで後側のLEDモジュール42b,42dが消灯するように制御してもよい。この場合、乗員に向かってゆっくりと光が流れて来るかのような演出効果を発揮させることができる。また、有色の光を照射するLEDモジュールを用いれば、徐々に色が変わるように見える演出効果を発揮させることも可能である。さらに、側部照射手段42を消灯するときに、4本のLEDモジュール42a〜42dの照度を徐々に下げるように制御すれば、座席6に着座した乗員に向かって、より滑らかに光が移動してくるかのような演出効果を発揮させることが可能である。
The present invention is not limited to the above embodiment.
For example, when the lighting mode A is switched to the lighting mode B, the four LED modules 42a to 42d constituting the side irradiation means 42 are not turned off all at once, but the front LED modules 42a and 42c are turned off first. Then, the rear LED modules 42b and 42d may be controlled to be turned off. In this case, it is possible to exert a production effect as if light slowly flows toward the passenger. In addition, if an LED module that irradiates colored light is used, it is also possible to exhibit an effect that looks like the color gradually changes. Further, when the side illumination means 42 is turned off, if the illuminance of the four LED modules 42a to 42d is controlled to gradually decrease, the light moves more smoothly toward the occupant seated on the seat 6. It is possible to produce a production effect as if coming.

上記実施の形態では、前から1列目の座席4が「第2の座席」であり、前から2列目の座席6が「第1の座席」である例を示したが、このような態様に限定するものではない。例えば、前から2列目の座席6が「第2の座席」であり、前から3列目の座席8が「第1の座席」である場合でも、上記実施の形態と同様に実施することが可能である。これらの両方を同時に実施する場合には、前から2列目の座席6に対して、その前列の座席4に取付けられた照射手段に連動する「着座検出手段」と、その後列の座席8に取付けられた着座検出手段に連動する「照射手段」の両方が取付けられることになる。要するに、本発明に係る車両内照明装置は、前後に設置される一対の座席に対してであれば、いずれの座席に対しても適用することが可能である。   In the above embodiment, the example in which the seat 4 in the first row from the front is the “second seat” and the seat 6 in the second row from the front is the “first seat” is shown. It is not limited to the embodiment. For example, even when the seat 6 in the second row from the front is the “second seat” and the seat 8 in the third row from the front is the “first seat”, the same operation as in the above embodiment is performed. Is possible. In the case where both of these are performed at the same time, the “sitting detection means” linked to the irradiation means attached to the seat 4 in the front row and the seats 8 in the rear row for the seats 6 in the second row from the front. Both “irradiation means” linked to the attached seating detection means are attached. In short, the in-vehicle illumination device according to the present invention can be applied to any seat as long as it is a pair of seats installed at the front and rear.
